Qwen3.8-27B, text and vision, in an 11.8 GB model file plus a 0.9 GB vision projector: 4.6x smaller than the 16-bit original, within 0.5% of its perplexity, and the perplexity of the 4-bit standard at 30% fewer bytes. 3.47 bits per parameter. Runs on a single 16 GB GPU. Opti 27B is Qwen3.8-27B, 27 billion parameters with vision through a projector file, compressed with Opti, a patent-pending compression method. The 16-bit original is 54.7 GB. This file is 11.8 GB, at 3.47 bits per parameter over the whole file, and on wikitext-2 it lands at 1.005x the original's perplexity. Paired window by window against llama.cpp's Q4KM, the 4-bit standard, it is statistically indistinguishable at 29.5%…
